WebSep 5, 2024 · Taken together, the results from Arabidopsis, rice, and legumes highlight our limited insight into the composition and mechanisms of plant receptor complexes that distinguish chitinaceous signal molecules. Since PAMP receptors and defense reactions were primarily studied in leaves, our insight into roots that must accommodate rhizobial … WebSep 1, 2024 · Significance Like 80–90% of land plants, legumes form endosymbioses with arbuscular mycorrhizal fungi, host endophytes, support a rhizosphere community, and are attacked by pathogens.
Chitin-induced Activation of Immune Signaling by the Rice
This review focuses on a comparison of plant reception of chitin oligosaccharides by legumes and rice. Chitin oligosaccharides (dp=6-8) released from fungal pathogens induce plant defense reactions in rice, while lipo-chitin oligosaccharides (dp=4-5) induce the development of a new plant organ, the nodule, in legumes during infection by rhizobia. … WebSep 17, 2014 · In A. thaliana, CERK1 forms a homodimeric complex and perceives chitin by itself (Liu et al. 2012) whereas rice OsCERK1 requires another LysM protein, CEBiP (chitin elicitor-binding protein), for the recognition of chitin oligosaccharides (Shimizu et al. 2010), indicating the difference in the chitin receptor systems between these model plants. dust free bathroom
Lipochitooligosaccharide recognition: an ancient story
WebAug 7, 2024 · An adjacent motif modulates the specificity for Nod factor recognition and determines the selection of compatible rhizobial symbionts in legumes. We also identified how binding specificities in LysM receptors can be altered to facilitate Nod factor recognition and signaling from a chitin receptor, advancing the prospects of … WebEstablishment of the Rhizobium–legume symbiosis depends on a molecular dialogue, in which rhizobial nodulation (Nod) factors act as symbiotic signals, playing a key role in the control of specificity of infection and nodule formation.Using nodulation-defective (Nod −) mutants of Medicago truncatula to study the mechanisms controlling Nod factor … WebJan 21, 2014 · To clarify the molecular basis of the specific recognition of chitin oligosaccharides by the rice PRR, CEBiP (chitin-elicitor binding protein), as well as the formation and activation of the receptor complex, biochemical, NMR spectroscopic, and computational studies were performed.
